Connect your JavaScript project to GlitchTip

Install the sentry browser SDK:

npm install @sentry/browser

Initialize the SDK as early as possible during page load:

import * as Sentry from "@sentry/browser";

Sentry.init({
  dsn: "YOUR_DSN",
  tracesSampleRate: 0.01, // 1% of transactions — adjust to your needs
  autoSessionTracking: false, // GlitchTip does not support sessions
});

Verify your setup by triggering a test error:

myUndefinedFunction();

Source Maps

Upload source maps for readable stack traces in production. Use the GlitchTip CLI:

glitchtip-cli sourcemaps inject ./dist
glitchtip-cli sourcemaps upload ./dist --org my-org --project my-project

Tips

  • Set tracesSampleRate to a low value in production to save disk space. Most teams find 1–10% sufficient for useful performance data.
  • Use release and environment options to track which deployments introduce errors.
